Downfall

The AMD Ryzen 7 5800XT and AMD Radeon RX 6600 pairing in Downfall shows a clear performance hierarchy dictated by resolution, with the GPU acting as the primary scaling factor. The data indicates that as resolution increases from 1920x1080 to 3840x2160, the average frame rates across all settings drop substantially, revealing a system that is heavily dependent on the graphics card's capabilities at higher pixel counts. At 4K with Low settings, the combo achieves 78 FPS, which represents a 55% reduction from the 175 FPS seen at 1080p Low, underscoring how quickly the RX 6600’s rendering workload intensifies. This pattern is consistent across the board: moving from 1080p to 1440p at High settings reduces average FPS from 117 to 84, a 28% decline, while the jump from 1440p to 4K at the same settings further drops performance from 84 to 52 FPS, another 38% loss. The scaling suggests that at 1080p and 1440p, the CPU is capable of feeding the GPU efficiently, but the Radeon RX 6600 becomes the limiting component as the resolution climbs toward 4K, where the pixel throughput demands exceed what this mid-range card can sustain.

Resolution Scaling

The frame rate scaling from 1080p to 4K in Downfall illustrates a classic GPU-bound scenario, particularly at higher detail settings. At Low settings, the average FPS falls from 175 at 1920x1080 to 125 at 2560x1440, a 29% drop, and then to 78 at 3840x2160, another 38% decline from the 1440p figure. This steep progression indicates that even at the lowest graphical preset, the RX 6600’s rendering pipeline is overwhelmed by the 4K resolution, where the total pixel count is roughly four times that of 1080p. The data also shows that the gap between settings widens at higher resolutions: at 1080p, the difference between Low and Ultra is 102 FPS (175 vs. 73), while at 4K, that same spread shrinks to 45 FPS (78 vs. 33). This compression of performance at 4K suggests that the GPU’s raw compute limits—its shading units and memory bandwidth—are being saturated regardless of the visual complexity, making the preset choice less impactful at the highest resolution.

At 2560x1440, the combination of the Ryzen 7 5800XT and RX 6600 delivers a more balanced experience. The Medium preset at 1440p produces 102 FPS average with a minimum of 87 FPS and a maximum of 117 FPS, indicating that the system has enough headroom to handle this resolution without severe frame pacing issues. The transition from 1440p Medium to 1080p Medium shows a 40% increase in average FPS (102 to 143), which aligns with the expected pixel count reduction. However, the 4K Medium result of 64 FPS, with a minimum of 54 FPS, falls below the 60 FPS threshold that many users consider playable, suggesting that 4K is only viable with Low settings, where the 78 FPS average provides a smoother experience. The scaling pattern strongly implies that the RX 6600 is the bottleneck at 4K, as the CPU’s performance metrics—such as its Cinebench R23 multi-core score of 23794—are more than sufficient to handle the game's logic at any resolution.

GPU Role

The AMD Radeon RX 6600, based on the RDNA 2.0 architecture with the Navi 23 chip, plays a decisive role in Downfall’s performance, particularly at higher resolutions. The GPU’s 8 GB of GDDR6 memory on a 128-bit bus provides 224.0 GB/s of bandwidth, which is a critical factor for texture streaming and frame buffer operations in a horror game that likely uses dense environmental details. The boost clock of 2491 MHz and game clock of 2044 MHz allow the card to reach a peak FP32 throughput of 8.928 TFLOPS, but the data shows that this compute capacity is insufficient for 4K Ultra settings, where the average FPS drops to 33. The GPU’s 1792 shading units and 64 ROPs are tasked with filling 3840x2160 pixels, and the 4K results indicate that the card’s pixel fill rate of 159.4 GPixel/s is a limiting factor, as the Ultra preset at 4K yields less than half the FPS of the Low preset at the same resolution.

The VRAM capacity of 8 GB does not appear to be a bottleneck in the measured scenarios, as the medium preset at 4K—which likely uses more memory than low—still achieves 64 FPS average, suggesting that the card’s memory subsystem can keep up with the game’s demands up to that point. However, the Ultra preset at 4K produces 33 FPS, which could indicate that the combination of increased texture detail and higher resolution exceeds the memory bandwidth’s effective capacity, causing the GPU to stall. The GPU’s percentile ranking of 63 among all tested GPUs, with an average benchmark score of 19036, places it in the mid-range tier, and its nearest rivals—such as the NVIDIA Quadro K6000 with a 0% delta and the GeForce RTX 4050 Mobile with a -0.1% delta—show that the RX 6600 is competitive with these older or mobile parts, but none of them are designed for high-refresh 4K gaming. The data confirms that for Downfall, the RX 6600 is best suited for 1080p and 1440p gaming, where its performance aligns with its 63rd percentile standing.

How This Combo Ranks

In the comprehensive database of tested combinations for Downfall, the AMD Ryzen 7 5800XT paired with the AMD Radeon RX 6600 ranks 2889 out of 3716 total combos, placing it in the lower-middle portion of the distribution. This rank of 2889, which corresponds to the 22nd percentile of all tested configurations, reflects the GPU’s mid-range positioning rather than the CPU’s strength. The Ryzen 7 5800XT itself is a high-performing processor, evidenced by its 81st percentile ranking among all CPUs and an average benchmark score of 29879, but the combo’s overall standing is dragged down by the RX 6600’s 63rd percentile GPU score. This disparity suggests that the CPU is not the limiting factor in most scenarios, and the combo’s rank is primarily a function of the graphics card’s capabilities. Compared to other pairings in the database, this configuration sits above the bottom 22% of systems, meaning that while it can handle Downfall at lower resolutions, it is not competitive with high-end GPU pairings that dominate the upper ranks.

The delta between the CPU and GPU performance tiers is notable: the Ryzen 7 5800XT’s nearest rivals include the AMD Ryzen 7 7840H with a 0% delta and the Ryzen 5 9600X with a 0.6% delta, indicating that the CPU is on par with modern mid-range processors. In contrast, the RX 6600’s nearest rivals are older or lower-power parts, with the Quadro K6000 matching it exactly at 0% delta and the RTX 4050 Mobile trailing by -0.1%. This asymmetry means that the combo’s rank of 2889 is likely higher than what the GPU alone would achieve, as the CPU’s strong single-thread and multi-thread scores—such as 3359 in Cinebench R23 single-core and 23794 in multi-core—help maintain frame consistency in CPU-bound sections of the game. The benchmark data indicates that this combo is a sensible pairing for 1080p gaming, but its rank in the database suggests that users seeking 4K performance would need to upgrade the GPU to move significantly higher in the standings.

Measured FPS Breakdown

The measured FPS data for Downfall provides a detailed look at how the Ryzen 7 5800XT and RX 6600 handle different settings and resolutions. At 1920x1080, the system delivers strong performance across the board: Low settings produce 175 FPS average, Medium achieves 143 FPS with a minimum of 122 FPS and a maximum of 164 FPS, High reaches 117 FPS, and Ultra still manages 73 FPS. These numbers indicate that at 1080p, the combo is well-suited for high-refresh-rate monitors, as even the Ultra preset stays above 70 FPS, providing a smooth experience for the horror genre’s tense gameplay. Moving up to 2560x1440, the performance drops are noticeable but not crippling: Low yields 125 FPS, Medium produces 102 FPS with a minimum of 87 FPS and a maximum of 117 FPS, High achieves 84 FPS, and Ultra falls to 52 FPS. The 1440p results suggest that the system is capable of handling this resolution with Medium or High settings for a balanced experience, but Ultra may be too demanding for consistent frame rates.

At 3840x2160, the limitations of the RX 6600 become apparent. Low settings produce 78 FPS average, which is playable but not ideal for a horror game that benefits from smooth motion. Medium settings drop to 64 FPS with a minimum of 54 FPS and a maximum of 73 FPS, placing it just above the 60 FPS threshold but with some frame dips that could be noticeable during fast-paced sequences. High settings reduce the average to 52 FPS, and Ultra falls to 33 FPS, which is likely too choppy for an enjoyable experience. The 4K data shows a clear pattern: the RX 6600 can handle Low and Medium settings at 4K, but High and Ultra presets are not viable for smooth gameplay. The minimum FPS values, where available, provide additional context—the 1440p Medium minimum of 87 FPS and 1080p Medium minimum of 122 FPS indicate that the system maintains good frame consistency at lower resolutions, whereas the 4K Medium minimum of 54 FPS suggests occasional stutters that could affect immersion.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend heavily on the target resolution. At 1920x1080, the Ultra preset at 73 FPS provides the best visual quality while maintaining a playable frame rate, making it the recommended choice for users who prioritize graphics fidelity. The High preset at 117 FPS is also excellent for those with 144Hz monitors, as it offers a significant boost in smoothness without sacrificing too much visual detail. For 2560x1440, the High preset at 84 FPS strikes the best balance, delivering solid performance that stays well above the 60 FPS threshold while offering improved visuals over Medium. The Medium preset at 1440p, with its 87 FPS minimum, is a safer choice for users who experience sensitivity to frame drops, as it provides a more consistent experience, but High is generally the sweet spot for this resolution.

At 3840x2160, the recommendations shift dramatically. The Low preset at 78 FPS is the only setting that provides a consistently smooth experience, and it is the recommended choice for 4K gaming with this combo. The Medium preset at 64 FPS is also playable, but the 54 FPS minimum could lead to noticeable hitches in Downfall’s atmospheric scenes, so users should weigh the visual improvements against the risk of frame dips. High and Ultra at 4K are not recommended, as 52 FPS and 33 FPS respectively fall below the threshold for comfortable gameplay in a horror title where responsiveness is key. For users with 1440p monitors who want the best experience, the High preset offers the strongest combination of visuals and performance, while 1080p users can confidently enable Ultra for the full graphical experience. The data suggests that this combo is best utilized at 1080p with Ultra settings or 1440p with High settings, as these configurations maximize the system’s capabilities without overburdening the GPU.

CPU Role

The AMD Ryzen 7 5800XT plays a supporting but crucial role in Downfall’s performance, particularly at lower resolutions where the GPU is less stressed. This 8-core, 16-thread processor based on the Zen 3 architecture (Vermeer) operates with a base clock of 3.80 GHz and a boost clock of 4.80 GHz, providing ample single-thread performance for game logic and physics. The CPU’s benchmark results are impressive, with a Cinebench R23 multi-core score of 23794 and a single-core score of 3359, placing it in the 81st percentile of all CPUs. In Downfall, a horror game released in 2016, the CPU’s capabilities are more than sufficient to handle the game’s thread requirements, as evidenced by the 175 FPS at 1080p Low, which indicates that the CPU is not a bottleneck at this resolution. The transition from 1080p to 1440p at Low settings shows only a 29% drop in FPS (175 to 125), which aligns with the increased pixel count rather than a CPU limitation.

The Ryzen 7 5800XT’s 32 MB of shared L3 cache and 4,150 million transistors on a 7 nm process provide low-latency access to frequently used data, which is beneficial for maintaining consistent frame times in Downfall’s unpredictable horror sequences. The CPU’s 16 threads are likely underutilized in this game, as the 3DMark 16-thread score of 7683 and max-thread score of 7680 show that multi-threaded scaling is strong, but the game’s engine probably relies more on single-thread performance, where the CPU excels with a 3DMark single-thread score of 959. The data shows that at 4K, the CPU’s role diminishes further, as the GPU becomes the primary constraint—the 4K Low FPS of 78 is nearly identical in ratio to the 1440p results, indicating that the CPU is not holding back performance at higher resolutions. The CPU’s 105 W TDP and support for DDR4 memory with 51.2 GB/s bandwidth ensure that it can feed the GPU without memory bandwidth limitations, making it a solid partner for the RX 6600 in this title.
